It's not built into Python, but it's easy to roll our own computation for it: def cardLuhnChecksumIsValid(card_number): """ checks to make sure that the card passes a luhn mod-10 checksum """ sum = 0 num_digits = len(card_number) oddeven = num_digits & 1 for count in range(num_digits): digit = int(card_number) if not (( count & 1 ) ^ oddeven): digit = digit * 2 if digit > 9: digit = digit - 9 sum = sum + digit return (sum % 10) = 0 Validating credit card number using Luhn Algorithm, Verifying Credit and Debit card using python script, Python code to validate the credit card number.
